BTW, I tried the "Irish Air" website G8AFN recommended and couldn't find any beacon listing there except on an individual basis airfield by airfield. Anyway, it only lists air beacons, not maritime.
correction, sorry: see http://web.inter.nl.net/hcc/Shortwave/B001.htm and subsequent pages for a list of beacons logged in the Netherlands. 73, Alan, G3XZX
